Plone 5.2, the Future-Proofing Release
After 3.5 years of development, the Plone community has released Plone 5.2 that includes Python 3 compatibility, a REST API in core, and the latest Zope 4.
An update to secure the future
Plone 5.2 is the latest version of the most fully-featured, open source web content management system. Plone 5.2 is the culmination of over 3.5 years of development that was driven by the looming deadline of January 1, 2020: the impending end of support for Python 2.x.
Python 3 Compatibility
Plone is written in
, the programming language that has taken the world by storm and is popular for learners, scientists, web developers and machine learning alike. Support for Python 3.6, 3.7, and 3.8 is now included with Plone 5.2, opening up the future for Plone’s continuing 20 year reputation for unrivaled security and stability.
Plone 5.2 ships with
, which itself comes with Python 3 compatibility, Web Server Gateway Interface (WSGI) support, and a new look.
Work on Plone 5.2 began to take shape in January 2016, with a Plone Improvement Proposal (PLIP) to
to use early Zope4 versions and culminated in the completion of the proposal to
in February 2019.
REST API
Once available as a separate add-on, a REST API is now also included in Plone 5.2, making it even easier to use Plone with modern JavaScript front ends such as Volto (based on React) and to integrate Plone with other applications.
User-Facing and Developer-Focused Changes
But Plone 5.2 isn’t just a backend upgrade: it includes user-facing features such as new dropdown menus, configurable redirects (customizable URL shortening and content linking).
Developers will also find a more pluggable and customizable login mechanism and a modernized virtualenv-based buildout.
Community-driven development
For almost 20 years now, the Plone software has continued to innovate and evolve with the times, and its world spanning community maintains a dynamic schedule of collaborative sprints and an annual conference bringing together its integrators and users, which include corporations, universities, all levels of governments and well-known government agencies.
Feature-rich and ready-to use
Plone is unsurpassed its out of the box experience for collaboratively creating, maintaining, and managing large amounts of content. Some of its feature highlights include:
customizable workflow for controlling how content gets reviewed and published
built in content history and version control

sophisticated, fine-grained security through permissions, roles, users, groups, and folder- and object-level sharing authorization
accessibility compliance, meeting WCAG 2.1 AAA
integration with enterprise authentication and authorization via LDAP/ActiveDirectory
deployments that scale, whether Docker, on-premise, or in the cloud
Future Proofing
Plone 5.2 is a must-have as of January 1, 2020, for individuals and organizations with complex content serving needs, a rigorous publishing workflow, a multi-person content creation team, or all of the above.
